All the settings that i mentioned above are in the UsersWP plugin. The users that i am talking about are the ones who are registering on my website to gain access to listing page & other stuff meant for registered users only.
Please see the UsersWP screenshot where I have disabled the email options.
it didn’t work for me. wp_logout_url() function is already defined in my php… But i managed to logout completely using a different link and redirection url.
Any inputs/ resolution for points i mentioned as c and d in my initial post.
